Five advantages of FRP grille over traditional grille!
FRP grating is a kind of glass fiber reinforced material and unsaturated polyester resin as the matrix material. It is a kind of plate-like material with many spaces that is compounded by a special processing process. It has excellent characteristics such as light weight and high strength, corrosion resistance, flame retardant, and anti-skid. It is widely used in floors, trench covers, platforms, and ship decks. and other industries. However, it is precisely because FRP grating plays an irreplaceable role in people's lives that FRP grating manufacturers for industrial floors can be seen almost everywhere.
Continuous filament winding process (belonging to continuous method): The process is that the tube is pre-impregnated with a supply resin in motion Feed station for roving, chopped fiberglass and resin sand mixture, the tube is made in the continuous advance of the mandrel.
Traditional grilles are easy to age and rust, have low strength levels, and cannot resist the corrosion of the atmosphere and acid and alkali salts. FRP grating solves the shortcomings of traditional grating well, and is affordable and corrosion-resistant, becoming an alternative to old-fashioned steel gratings, plastic gratings and metal gratings.
FRP grating is made of resin and glass fiber, and its density is small, compared with steel grating, The density of FRP grating is only 1/4 of steel and 2/3 of aluminum, and its strength is 10 times that of rigid PVC, which is stronger than aluminum and reaches the level of ordinary steel. Its light weight can greatly reduce the foundation support and reduce the material cost of the project. It is easy to cut and install, no need for hot work and large lifting equipment, only a small amount of labor and power tools, which greatly reduces the installation cost.
High-quality FRP grating products have no obvious cracks in appearance, fewer pores, pure colors, good transparency, and have It has certain toughness, high strength, good surface finish and long service life; while inferior FRP grating products have cracks in appearance, more pores, impure color and insufficient gloss. Its service life is also shorter.
The FRP grating has won unanimous praise in the industry and has an opening rate of 68%, which can handle the above results. The more consumers of tree combs emerge, the more forms of cooperation emerge. .It won't be as dense as the rest of the tree comb, but it won't help bamboo growth. .Good tolerance. FRP grating is a lattice hollow material without protection: the field of anti-corrosion protection is in a relatively reluctant state, and through the use of landscaping designs, it is more resistant to rain and snow corrosion.
The raw materials used for FRP grating are resin, FRP fiber wire, and calcium powder as filler in 1:1:1 The proportion of the configuration, high-quality FRP grille selection of high-quality resin: unsaturated phthalic resin 196, colorless and transparent. Low viscosity, low exotherm, low shrinkage, high speed curing, high speed compatibility, bright gloss. The produced FRP grating is flat and smooth, with good gloss, high strength and certain toughness. If you use inferior resin, it will be completely opposite. The inferior resin is cloudy, high viscosity, high exotherm, high shrinkage, relatively slow curing, and poor compatibility. Toughness is not good.
Reciprocating filament winding process (belonging to fixed-length method): In this process, the dipping tank rotates with The mandrel moves back and forth, and the long fiber glass filaments are placed at a certain oblique angle relative to the mandrel axis. The auxiliary angle (ie the winding angle) is controlled by the ratio of the moving speed of the dip tank and the rotational speed of the mandrel, and the translational movement of the dip tank By computerized electro-mechanical control. The number of winding layers is gradually increased until the designed wall thickness is reached. After the winding is completed, the resin in the article is substantially cured. After curing, the mandrel is removed from the fiberglass pipe.
The raw materials of FRP grid are resin, glass fiber and calcium powder filled with 1:1. The high-quality FRP mesh is made of high-quality resin: unsaturated phthalic resin 196, colorless and transparent. Low viscosity, low exotherm, low shrinkage, high speed curing, high speed compatibility, gloss. The produced FRP mesh is smooth, smooth, shiny, strong and has a certain toughness. If poor quality resin is used, it will do the exact opposite. Inferior resins are cloudy, high viscosity, high exotherm, high shrinkage, relatively slow curing, and poor compatibility. The produced FRP meshes are porous, easily fractured, and have poor strength and toughness.
